IMPROVEMENT IN APPARATUS FoR CASTING BULLETS.

Specification ,forming part of Letters Patent No. 35,320, dated MayQO,1862.

`Be it known that I,EDWI'N MAY, of Indi-- anapolis, in the county ofMarion and State of Indiana, haveinvented a certain new and usefulImprovement i'n the Mode of Casting Gonical and Hollow Bullets, of whichthe followl ing is a full and exact description thereof, reftion, l will`proceed todescribe its construction and operation. y

Figure 1, A, side view of machine made of malleable iron; B, endofkettle made of eastiron; Fig. 2, A, plan or topviewof machine; B, planof kettle; Fig. 3, B, side view of kettle; Fig. 4, section throughkettle; Fig. 5, machine A inverted; Fig. 06, top of adjustable molds t't',- Fig. 7, inside view or one-half of I place the pig-lead in e'. There being below the same, the lead is melted and passed through the `portu into o and raised until it reaches the dotted line p p, when,acting ony the governor r, it closes the port u with the valve t.

" there is no dross to skim off by this method, a

large saving of laborand lead is effected. Having securedthe level` andsupply of melted lead s in o, I proceed to cast the bullets floy placingthe machine A Within kettle B at o. The melted l lead fills the mold t't', and is then shoved along over the lifts and stops 1 1,which elevatesthe machine so that the mout-l1 of molds is out of the melted lead. ctby removing the catch q, which allows the plungers hh and k la to beforced down by means of the springs e e e e, h IL to press on the bulletand cut off the surplus lead, and 7c k to press within the bullet,thereby'swaging the same to a perfect outside surface. lead taken up bythis operation is replaced from z by melted lead passing through theport u. After cooling I proceed to remove the bullets, which is done byputting down the lever a under catch q and releasingthe lever d byraising the same, when the springs e e e e, acting on the lever a overthe hinge and fulcrum g, open the machine, and the'bullets fall out,ready for use without further preparation. The molds z' 'i aremade'adjustable, so that to change the form of bullets itis onlynecessary to draw the screws n n n n and place other molds instead. ingthe same together by means of the lever d insures a perfect joint, andno expansion under heat will affect the same.

What I claim, and desire to secure by Letters Patent, is-

l. The casting of conical and hollow bullets and swaging the same Whilethe lead is in a plastic state by means ofthe molds z' i, in combinationwith the plungers h h 7c k, and the springs e e ee, when constructed andoperated substantially as and for the purposes set forth.

2. The adjustable molds z' i and clamps j j,

in combination with the levers a and d, when constructed and operatedsubstantially as and for the purposes set forth.
